The cost to society of physical injury related to alcohol consumption is immense – the link between severe alcohol intoxication, road accidents and violence is well established. Now new research from the Swedish Karolinska Institutet medical university indicates that most alcohol-related damage occurs after moderate consumption. While people who have drunk considerable quantities of alcohol suffer higher injury risk than people who have drunk only a little, the research shows the risk of suffering injury increases significantly after small amounts of alcohol as little as one glass.
